Title: Vertical field effect transistor
Inventor: TAKAHASHI YOSHITOMO
IPC: H01L29/06
Filed: 1988-04-01
Abstract: PURPOSE:To provide high speed and high output switching performance by a method wherein the impurity concentration distribution of a connection region which connects a source region to a drain region through a channel is such that the concentration near the surface of the connection region is lowered to the extent nearly the same as the concentration of the drain region. CONSTITUTION:After a low impurity concentration n<->-type drain region 2 is formed on a high impurity concentration n<+>-type semiconductor substrate 1 by epitaxial growth, n-type impurity ions are implanted to form an n<+>-type connection region 3a. Further, p-type impurity ions are implanted into the connection region 3a to dilute the n-type impurity concentration in the surface of the n<+>-type connection region 3a near a gate oxide film and an n<->-type connection region 3b whose impurity concentration is nearly the same as the concentration of the low impurity concentration n<->-type drain region 2 is formed. Then a p<+>-type base region 4, an n<+>-type source region 6, a source electrode 9 and a drain electrode 10 are formed. With this constitution, high speed switching can be realized without losing high output switching characteristics.

Title: Liquid-level detector
Inventor: MARUYAMA HIROAKI
IPC: G01F23/292
Filed: 1979-06-29
Abstract: PURPOSE:To obtain a liquid-level detector being compact and having improved accuracy and reliability by optically connecting a light-emitting element and a photoactive element which are connected together through conductors on a wiring board, with a pair of optical fibers having one end formed into a total reflection face, and installing this in a given container together with conductors to the elements. CONSTITUTION:Lead wires 29-32 of a light-emitting element 21 and a photoactive element 22 are connected to conductors 33-35 through a wiring board 24. A pair of optical fibers 27a and 27b having a junction portion 28a whose one end 28 is a total reflection face are contacted with the light-emitting element 21 and the photoactive element 22 through a holding member 25 and a supporting member 26, and optically connected. The detector is inserted into, e.g., a container 42 monolithicly provided to a discharge port 41a of a discharge portion 41 of an electrically-operated pump, and fixed. When the level of the liquid flowing in from a lower part 43 reaches the total reflection face 28b, light from the light-emitting element 21 is no longer applied to the photoactive element 22, so that the liquid level can be sensed. Thus, the detector being compact and having improved accuracy and reliability can be obtained.

Title: Picture recorder
Inventor: HIROMATSU KENJI
IPC: G02B26/10
Filed: 1991-03-20
Abstract: PURPOSE:To improve the extension distortion of a picture recorded in a main scanning direction when recording pictures while scanning optical beam in the main scanning direction at inconstant speed. CONSTITUTION:Pulse signals PS obtained by scanning second laser beam L2 on a grating sensor 13 is inputted to an input terminal 71 of a PLL circuit 40. The PLL circuit 40 stabilizes systems, resulting in delaying the phase of an output signal VX of an amplifier 42b. On the other hand, a function generation circuit 50 outputs an analog signal represented by the prescribed function while synchronizing with a driving clock CL formed by the pulse signals PS as a correction signal VS. The phase of this prescribed function proceeds by adding the output signal VX with the correction signal VS in an analog adder 46. Therefore, an exposure clock ECL beams an ideal optical modulation clock without phase delay.

Abstract: PROBLEM TO BE SOLVED: To precisely detect a position with simple device and procedure by measuring the inclination of a rotating shaft every vertical movement of a specified quantity of the rotating shaft and every interval of a prescribed time by an inclinometer on the tip of the rotating shaft and a depth indicator followed by arithmetic operation. SOLUTION: The measured value of an inclinometer 6 on the center in the tip of a rotating shaft 1 is transmitted to a receiver 12 on a support arm 5 through a transmitter 11 or the like. On the other hand, a proximity switch 13 outputs a pulse signal every rotation of the rotating shaft 1, and detects the inclination signal from the inclinometer 6 every time. A depth indicator 14 is provided on a leader 3 side to detect the moving quantity of the rotating shaft 1 tip. These signals are inputted to a computer and arithmetically operated. Namely, the difference between two inclinometer output values in positions symmetric to the origin on X-axis and Y-axis passing the shaft center of the rotating shaft 1 is halved. The respective values are calculated as t X-axial and Y-axial inclinations of the rotating shaft to vertical axis.  The position of the rotating shaft 1 tip is calculated by the inclination and the penetration measured value of the rotating shaft 1 tip from the depth indicator 14.

IPC: H03M1/12
Filed: 1985-04-19
Abstract: PURPOSE:To prevent the emphasis of noise component by dividing the input sound signals into plural bands for coding after normalization, then turning those coded signals into the coding signals after correcting by a correction level. CONSTITUTION:The input sound signals are divided into plural bands e.g., low, medium and high bands by a band dividing filter 1 and applied to normalizing parts 2a-2c for normalization. These normalized signals are coded by coders 3a-3c for each band and applied to correcting parts 4a-4c. A control part 5 decides the frequency characteristics of the input sound signals from the peak detecting values of the parts 2a-2c and controls the normalizing levels of the parts 2a-2c as well as the correcting levels of the parts 4a-4c for each band. Then the signals underwent the level corrections are delivered as the coding signals corresponding to each band or multiplexed by a multiplexer 6 for output. This prevents the increase of the noise level.
